This invention relates to improvements in nstruments for use incaponlzing operations and has for its primary object to provide aninstrument so designed that positive engage- 5 ment of the thread orcord supporting the organ to be removed may be accomplished so u thatseverance of the cord can be effected quickly and easily.

Another object of the invention is to provide an instrument of the abovedescribed character so designed that it may be held and manipulated withone hand while the other hand is left free for holding the fowl, thusmaking it possible for a person to perform the operation withoutassistance.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawing forming a part of the present invention, with the understanding,however, that the invention is not confined to any strict conformitywith the showing of the drawing but may be changed or modified so longas such changes or modifications mark no material departure from thesalient features of the invention, as expressed in the appended claims.

In the drawing Figure 1 is a'" plan View of the instrument embodying thepresent invention. 7

Figure 2 is a view in side elevation of the forward ends of the jaws.

Figure 3 is a sectional view taken upon the line 33 of Figure 1. r a

Figure 4 is a sectional view taken upon the line 44 of Figure 2. I

Figure 5 isa sectional view taken upon the line 5-5 of Figure 1.

Referring more particularly to the drawing wherein like numerals ofreference indicate corresponding parts throughout the several views, itwill be seen that the present improved caponizing instrument isgenerally in the form of a pair of scissors having the relatively longslender jaws 1, each of which at its rear end is formed to provide aflattened obliquely directed portion 2 which merges into a shank 3 whichin turn merges into and terminates in a loop 4 designed to receive afinger of the user. The'obliquely angled portions 2 of the jaws arearranged in crossed relation, as shown, and pivotally secured togetherby a suitable screw or rivet 5 so that by spreading the loops 4 theforward ends of the jaws will be moved apart, as willbe readilyunderstood.

The jaws terminate at their forward ends in the laterally directedfingers 6,- which fingers are adapted to be brought into side.

by side contacting relation when the jaws are closed and one of the jawshas formed integral therewith, upon its underface, a plate 7 whichnormally overlaps the underface of the adjacent jaw, as shown.

The shanks 3 which together form the handle of the instrument are soformed that when they are brought together they will be in relativelyclose relation at the points 8 which are adjacent the pivot point 5 andfrom these points they diverge slightly. the shanks carries the slidinglatch member 9 which has one end turned to form a hook 1O whichisnormally engaged over the adjacent shank. v v

In the use of the present instrument the latch 9 is firstmoved to theclosely spaced parts 8 of the shanks which permits the fingers 6 of thejaws to be opened slightly. After the formation of the necessaryincision, the instrument, held in the right hand with the forefingerupon the latch, has the finger carrying ends of the jaws inserted intothe incision and is then manipulated to position the cord between thefingers. The guard plate 7 acts to limit the movement of the cordbetween the fingers so that a positive engagement of the cord thereby iscertain.

The forefinger of the operator is then drawn back to pull the latch 9rearwardly upon the diverging arms or shanks 3 while' the operator atthe same time closes the handle to bring the fingers tightly togetheragainst the cord. The latch thus acts to maintain the jaws firmly closedand the operator is then enabled to give the necessary twisting andelevating movement to the instrument to remove the cord from the bodyofthe chicken so that the same can be easily reached to be cut with asuitable instrument From the foregoing description it will be One of hreadily seen that the present instrument may be inexpensively made andis designed to enable the user to work quickly and accurately without arisk of injuring and possiblylosing the fowl operated upon.

Having thus described my invention, what I claim is 2- 1. An instrumentof the character des scribed, comprising a pair of pivotally con nectedjaws each terminating at its forward end in a laterally directedfinger,said fingers being adapted to be broughtinto side by sidecontacting relation, a guard member carried by oneof the jaws normallyoverlapping the adjacent jaw, and means for securing the jaws in closedposition. I l

2. Inanj instrument of the characterdescribed, a pair ot'jaw members,means for pivotally connecting the jaws, fingers formed 00 at the endsof the jaws remote from the pivot point and adapted to be brought intosideby side relation, a guard plate carried byone of the jawstandnormally overlapping th r1d: jacent jaw and in close proximity to saidfingers, and means normally preventing separation of said jaws beyond apredetermined dis-,

tance adapted to be actuated forlocking the f jaws and fingers incontacting relation.

3. In an instrument of the character de- :cribed, a pair of pivotallyconnected jaws,

fingers carried by said jaws adapted to be brought into side by sidecontactingrelation,

a guardplate carried by one of the jaws and overlapping the adjacent jawbehind and in close proximity to saidfingers, handleshanks carried bysaid jaws and extending through a portion of their length in divergentrelation from apoint adjacent the pivotalfconnection of the jaws, and asliding latch mem- 40 her adapted when moved over the divergent ends ofthe shanks to lock the jaws and fingers in contacting relation.

In testimony whereof I hereunto aflix my signature. CLIFFORD F.CRIDLAND.
